This document discusses NodeJS and NoSQL databases. NodeJS is an evented I/O framework built on Google's V8 JavaScript engine that allows for server-side JavaScript. It introduces some common NodeJS packages like ExpressJS, Jade, Nodemon, and Node-inspector. It then discusses several NoSQL database types (document, key-value, columnar, and graph) and shows how NodeJS interfaces with popular NoSQL databases like CouchDB, MongoDB, Riak, Redis, Cassandra, and Neo4J through packages like Cradle, Mongoose, Riak.js, node_redis, and node-neo4j. The document benefits of NodeJS like speed and large

3. NodeJS: Server-side Javascript
Evented I/O framework
on top of
V8 javascript by Google

4. Node code
var http = require('http');
http.createServer(function (req, res) {
res.sendHeader(200, {'Content-Type': 'text/plain'});
res.sendBody('Hello World!');
res.finish();
}).listen(8000);
console.log('Listening on port 8000');

5. MVC in NodeJS
ExpressJS - Sinatra-like (in Ruby on Rails) web framework
Jade - html template

6. Useful NodeJS Development Packages
Node Package Manager (npm) - package installer
Nodemon - auto-detection node watcher
Node-inspector - browser-based debugger
Vows.js - Behavior-Driven Development (BDD)

7. More useful packages
Backbone.js - provides models, collections and views to
Javascript
Underscore.js - utility library to add functional programming to
Javascript: "a tie to JQuery's tux"
Socket.io - a package to help make realtime apps
Coffeescript - a little language that compiles into JavaScript

8. Benefits of NodeJS
Extremely fast
Event-driven
2 years old and already a huge community
Javascript all the way down

9. Pitfalls of Node
Boomerang-shaped code (solution: Step or Flow.js)
Javascript thinking-curve

11. NoSQL
* Document Database
* Key-Value Database
* Columnar Database
* Graph Database

12. Document DB - CouchDB/MongoDB

13. Key-Value Store - Riak/Redis

14. Column Store - Cassandra

15. Graph DB - Neo4J

16. Cradle = CouchDB + NodeJS
